Resumo

Um estudo integrado da Formação Atafona – depósitos lacustres da fase rifte da Bacia de Campos, Brasil – utilizando amostras de calha de um poço do pré-sal forneceu dados e interpretações inéditas sobre a litogeoquímica, mineralogia, ambiente deposicional e proveniência sedimentar de todo o intervalo perfurado da formação. As análises consistiram em fluorescência de raios X, espectrometria de massa com plasma indutivamente acoplado, difração de raios X – incluindo mineralogia das argilas – e microscopia eletrônica de varredura com espectroscopia de energia dispersiva, além da correlação com perfis do poço. O principal argilomineral identificado é a saponita, com características geoquímicas e texturais indicativas de autigênese, sugerindo um paleoambiente alcalino. Ciclos de períodos mais úmidos, marcados por maior aporte detrítico, e períodos mais secos, com um aumento na formação de carbonatos, foram identificados. Um aumento em fósforo, enxofre, dolomita e estrôncio na porção superior da Formação Atafona sugere um possível aumento na atividade microbiana. Razões elementares indicam uma proveniência de rochas ígneas ácidas a intermediárias para os grãos detríticos, enquanto propomos uma fonte máfica adicional de cálcio e magnésio fornecida por águas subterrâneas que fluíram através do embasamento basáltico.
